try:
	yt = YouTube(yt_path, on_progress_callback=onProgress)
	print(f"正在下載影片: {yt.title}")
	stream = yt.streams.filter(type="video",res="720p").first()
	streamss = yt.streams.filter(type="video")
	print(streamss)
	print(stream)
	stream.download()
	print(f"影片{yt.title}下載完成")
except IndexError as e:
	print("URL something error--404")
	print(e)

改進

使用

onProgress(stream, chunk, remaining)

來進行數據調顯示
我設定成每10%更新一次

total = stream.filesize
percent = (total - remaining) / total * 100
show_num=[10,20,30,40,50,60,70,80,90,100]
global sh_i
# print(sh_i)
if (percent > show_num[sh_i]) and (sh_i <= 8):
	print("下載中…{:05.2f}%".format(percent))
	sh_i=sh_i+1
else:
	pass
	#print("percent: ",percent)

改進:

  • 執行一次run三回下載
